In the coming season, we opened the window a little and put the wind, but since the cat opens the window without permission and goes outside, I was looking for something that could lock with something open in the window It was. I used it immediately, but it was a desired item.
Because it can cheaply and easily strengthen security of windows, I am planning to purchase it additionally. In order to lock it firmly, you need a lot of power, fingers will hurt if you do it with bare hands, so I would like to thank you if you can say that I can lock it a little easier.
